I guess what prompted me to ask was that I was thinking along the lines of:

If butt joints are adequate with the support of the surrounding strips (sort of an edge lamination), wouldn't 30 or 45 degrees give the aesthetic improvement that scarfing does with a little less work?

Someone mentioned using compound angles, which sounds like a strong joint. I was wondering why the angles are through the thickness rather than the width to begin with? Is it because of looks?
